You instead use the Channel Mixer, set it to grayscale, and put red at about 150% and constant at -50% (play with the sliders yourself to get it right). It gets better definition that way. It's quite annoying that Bob's composite looks better than my carefully balanced complicated images, but it does...

As you can see, while it technically achieves the saturation-contrast that Tom wants, on its own it still falls some way short of the desired effect.

I achieved this by:
- add a layer of solid red, and set its blend mode to Hue
- add a layer of solid red, and set its blend mode to Luminosity
- flatten
(this should leave you with an image that goes from gray to red)

- Image > Adjustments > Selective Colour, and on the page for Reds, whack the Black slider all the way to the left.
- Desaturate
- Use levels to narrow down on the range of colours in the image

- Use that map (Inverted) as a mask for a desaturated copy of the original layer.

The second pic looks a lot sharper, possibly a little too sharp for my liking. I like the girl on the right ;) The effect’s not bad, although I find the leaves are a bit distracting in this particular photo.

I wonder what a dupicate of the original image on the top layer using a Hue or Colour overlay would look like? Whether it would restore some of the original colour without losing the sharpness?
